Domestic paper standards
In China, two main specifications are used: (787×1092mm) and (889×1194mm) .
Youdaoplaceholder0 Zhengdu paper originated from the printing standards of the Republic of China and is suitable for traditional publications such as books and newspapers.
Youdaoplaceholder0 Large format paper introduced as part of the international ISO standard, suitable for large format printed materials such as posters and picture albums, and for larger sizes.
Iii. Printing Format and Cutting
Youdaoplaceholder0 Kels is the number of slices of a full sheet of paper, for example:
Youdaoplaceholder0 Straightening paper cutting example : 16k 190×260mm, 32K 130×190mm.
Youdaoplaceholder0 Large-sized paper cutting example : Large 16K 210×285mm, Large 32K 140×210mm.
Special formats (such as offset and variable formats) are used for asymmetrical design requirements.
Iv. Paper Technical Parameters
Youdaoplaceholder0 gram weight (basis weight) : Refers to the weight per square meter of paper (g/m²), for example, 157 grams of coated paper is thicker than 128 grams.
Youdaoplaceholder0 Print run and loss : The print run should include paper cover to compensate for cutting or printing error.
Youdaoplaceholder0 Paper type : including writing paper, coated paper, packaging paper, etc. The performance is adjusted by additives such as sizing agents and fillers.
V. Industry Trends and Technological Development
Youdaoplaceholder0 Environmental protection and circular economy : Increased recycling rate of waste paper, accelerated research and development of biodegradable materials.
Youdaoplaceholder0 Process optimization : Energy-saving equipment and wastewater treatment technologies reduce carbon emissions, such as membrane separation technology for purifying papermaking wastewater.
Youdaoplaceholder0 Intelligent production : Fully automatic pulp flow boxes and drying systems improve paper uniformity and production efficiency.
